BIPRU 8 Annex 1 (Decision tree identifying a UK consolidation group) shows that Articles 125 and 126 of the Banking Consolidation Directive are important in deciding whether the FSA is obliged to supervise a group or part of a group and hence whether that group or part of a group is a UK consolidation group. BIPRU 8 Annex 4 (Text of Articles 125 and 126 of the Banking Consolidation Directive) sets out these articles together with an explanation of how those articles should be read in the case of a group which also contains CAD investment firms.
